ABSTRACT:
After a door is super-locked by an electric motor, the door cannot be unlocked by a manual control knob for passenger's safety and for burglarproof. The door-lock unit and other components including the electric motor and a door-lock unit are protected from a violent force applied on the knob or some other components even if an inappropriate attempt to open the door in such occasion. In the actuator, an output lever which is connected to the door-lock unit rotatably disposed on an input lever which is connected to the knob. A clutch lever is connected to the torque transmitting mechanism and is rotatably disposed on the output lever. When the door is super-locked, the output lever is retained by a stopper, and only the clutch lever is rotated counterclockwise so that the clutch arm disengages from the input lever. As a result, even if the knob is drawn forcibly to unlock the door, only the input lever is rotated as the knob is moved and no violent force is applied on the door-lock unit or the electric motor.
